ANALYSING THE IMPACT OF THE PRODUCT LIFE CYCLE ON THE IMPORTANCE OF OUTSOURCING DECISION-MAKING CRITERIA: A MANUFACTURING CASE STUDY

<p>ENGLISH ABSTRACT: This study has been carried out to discover the impact of the product life cycle (PLC) on the importance of outsourcing decision-making criteria in a manufacturing firm. The four dimensions of outsourcing decision-making were identified, based on a literature review and on the conditions of the firm: (1) core competencies, (2) information leakage risk, (3) technological capability, and (4) cost. A case study and survey research were used, along with two non-parametric tests (Friedman’s test and Kendall’s W). The results show in particular that the importance of ‘technological capability’ and ‘strategic information leakage risk’ does not differ across the various PLC stages. The importance of ‘leakage risk of product volume information’ and ‘total cost’ change over different stages of the product life cycle are also addressed. For the latter two criteria, the probabilities of each rating related to each criterion importance have been estimated by ordinal logistic regression, and the weights of these criteria have been calculated at each stage of the product life cycle.</p><p>AFRIKAANSE OPSOMMING: Die navorsing ondersoek die invloed van produklewensiklus op die gebruik van buite leweransiers deur ’n vervaardigingsonderneming. ’n Besluitvormingsmetode word ontwerp en getoets deur skepping van ’n boeket van wiskundige gereedskap soos, onder andere, ordinale logistiese regressie en die logistieke funksie. Die metode word ten slotte afgerond met ’n keurige gebruik van die Wasigheidsleer.</p&gt

Make-or-Buy Decision Using Interval-Valued Intuitionistic Fuzzy COPRAS Method

International Conference on Intelligent and Fuzzy Systems, INFUS 2019 -- 23 July 2019 through 25 July 2019 -- -- 228529One of the central issues in strategic management is the determination of a firm’s vertical boundaries. Since almost all the publications in the literature are based on crisp measurements and evaluations for make-or-buy decisions, we proposed a multi attribute decision making method using interval-valued intuitionistic fuzzy COPRAS for make-or-buy decision assessment. An illustrative example is presented for a Turkish toy company. © 2020, Springer Nature Switzerland AG
